Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the

ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.

Answer:

The population of interest in this study is:

children between the ages of 5 and 15.

Step-by-step explanation:

In research methodology, the population of interest is the comprehensive group of individuals, institutions, objects, and so forth who possess some common characteristics that are the interest of the researchers.  In our example, the researchers are studying the relationship between honesty, age, and self-control. The common characteristic of the group in this case is the age group between the ages of 5 and 15.  This characteristic distinguishes the children of this age group from other individuals, institutions, objects, and so forth.

alexira [117]

Answer:

A = 328 tons, B = 79 tons.

Step-by-step explanation:

A + B = 407

A - B = 249

Cancel b out of the equation, then add the rest.

2A = 656, A=328 tons

A + B = 407, B = 407-328

B = 79 tons

Sally and dana take a walk in the park for every 5 strides that sally make dana makes 4 strides after sally makes 120 strides ho
olga_2 [115]

Dana made 96 strides.

Step-by-step explanation:

Given,

Ratio of Sally's stride to Dana's strides = 5:4

Strides made by Sally = 120

Let,

x be the strides made by Dana.

Ratio of Sally to Dana = 120:x

Using proportion;

Ratio of Sally's stride to Dana's stride :: Ratio of Sally to Dana

5:4::120:x

Product of mean = Product of extreme

4*120=5*x\\480=5x\\5x=480

Dividing both sides by 5

\frac{5x}{5}=\frac{480}{5}\\x=96

Dana made 96 strides.
